FUSB380C Autonomous USB Type-C™ Cable Marker onsemi FUSB380C Autonomous USB Type-C™ Cable Marker provides a turnkey solution with a small footprint and low power for passive Electronically Marked Cable Assemblies (EMCA). The FUSB380C eMarker IC provides the cable's characteristics to the Downstream-Facing Port (DFP). This device operates from VCONN power, and features a 28V tolerant VCONN and Configuration Channel (CC) to provide shorting protection to the VBUS. One FUSB380C IC can provide the electronic marking for passive EMCAs by routing VCONN through the Type-C cable. Two FUSB380C ICs can be used to bypass routing VCONN through the Type-C cable.
